DM74S03 Quad 2-Input NAND Gate with Open-Collector Outputs August 1986 Revised May 2000 DM74S03 Quad 2-Input NAND Gate with Open-Collector Outputs General Description This device contains four independent gates each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. Pull-Up Resistor Equations Where: N1 (IOH) = total maximum output HIGH current for all outputs tied to pull-up resistor N2 (IIH) = total maximum input HIGH current for all inputs tied to pull-up resistor N3 (IIL) = total maximum input LOW current for all inputs tied to pull-up resistor Ordering Code: Order Number DM74S03MX Package Number M14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow This device is only available in Tape and Reel.
